now im not looking at gettin anyhitng fancy for the time being but with these two types of amps would i be able to run this sub:

15" subwoofer
Max Power 1200Watts
Metallic P.P Injection Cone
Response Frequency 30-2000Hz
Sensitivity 90 + 3dB
Impendence 4 ohms
Twin Magnet 100 OZ
Voice Coil 50mm
RMS 600Watts

12" subwoofer
Max Power 1000 Watts
Metallic P.P Injection Cone
Response Frequency 30-2000Hz
Sensitivity 90dB
Impendence 4 ohms
Twin Magnet 100 OZ
Voice Coil 50mm
RMS 500Watts


and the speakers... wat type of power, for example if it says 400w 4-way can i run them or 300w 3-ways




i just want 2 6 inch in the front and 2 in the back and possible 2 12 inch subs... so how many of those amps will i need?
do i need 6 x 9 in the back and whats the max size that fits in the door pods? would i be able to fit a 6.5 or an 8 in?


so would this sound good and clear in the car load? and also is BOSS a good brand?

thanx for any help

Stay clear of BOSS for speakers they arent that well sounding. If you want some cheap but not bad sounding speakers look for Pioneer or jaycar brnaded ones.

If you're on a budget i'd suggest a monoblock to run the 2 subs and a 4 channel amp to run the front speakers. There is not so much need to amp up the rear speakers unless of course the back seats are used fairly regularly.
